Did you forget to add a:
void dtraceUserMarkerWrapper(Capability *cap, char *msg)
to Trace.c? It's only defined in Trace.h
I'm getting this error:
HC [stage 1] ghc/stage2/build/tmp/ghc-stage2
Undefined symbols:
"_dtraceUserMarkerWrapper", referenced from:
_stg_traceMarkerzh in libHSrts_thr.a(PrimOps.thr_o)
